      Linus Torvalds authored
      Pull user namespace related fixes from Eric Biederman:
       "As these are bug fixes almost all of thes changes are marked for
        backporting to stable.
      
        The first change (implicitly adding MNT_NODEV on remount) addresses a
        regression that was created when security issues with unprivileged
        remount were closed.  I go on to update the remount test to make it
        easy to detect if this issue reoccurs.
      
        Then there are a handful of mount and umount related fixes.
      
        Then half of the changes deal with the a recently discovered design
        bug in the permission checks of gid_map.  Unix since the beginning has
        allowed setting group permissions on files to less than the user and
        other permissions (aka ---rwx---rwx).  As the unix permission checks
        stop as soon as a group matches, and setgroups allows setting groups
        that can not later be dropped, results in a situtation where it is
        possible to legitimately use a group to assign fewer privileges to a
        process.  Which means dropping a group can increase a processes
        privileges.
      
        The fix I have adopted is that gid_map is now no longer writable
        without privilege unless the new file /proc/self/setgroups has been
        set to permanently disable setgroups.
      
        The bulk of user namespace using applications even the applications
        using applications using user namespaces without privilege remain
        unaffected by this change.  Unfortunately this ix breaks a couple user
        space applications, that were relying on the problematic behavior (one
        of which was tools/selftests/mount/unprivileged-remount-test.c).
      
        To hopefully prevent needing a regression fix on top of my security
        fix I rounded folks who work with the container implementations mostly
        like to be affected and encouraged them to test the changes.

      Bluetooth: Fix bug with filter in service discovery optimization · ea8ae251
      Marcel Holtmann authored
      The optimization for filtering out extended inquiry results, advertising
      reports or scan response data based on provided UUID list has a logic
      bug. In case no match is found in the advertising data, the scan
      response is ignored and not checked against the filter. This will lead
      to events being filtered wrongly.
      
      Change the code to actually only drop the events when the scan response
      data is not present. If it is present, it needs to be checked against
      the provided filter.
      
      The patch is a bit more complex than it needs to be. That is because
      it also fixes this compiler warning that some gcc versions produce.
      
        CC      net/bluetooth/mgmt.o
      net/bluetooth/mgmt.c: In function ‘mgmt_device_found’:
      net/bluetooth/mgmt.c:7028:7: warning: ‘match’ may be used uninitialized in this function [-Wmaybe-uninitialized]
        bool match;
             ^
      
      It seems that gcc can not clearly figure out the context of the match
      variable. So just change the branches for the extended inquiry response
      and advertising data around so that it is clear.

      mmu_gather: fix over-eager tlb_flush_mmu_free() calling · f045bbb9
      Linus Torvalds authored
      Dave Hansen reports that commit fb7332a9 ("mmu_gather: move minimal
      range calculations into generic code") caused a performance problem:
      
        "tlb_finish_mmu() goes up about 9x in the profiles (~0.4%->3.6%) and
         tlb_flush_mmu_free() takes about 3.1% of CPU time with the patch
         applied, but does not show up at all on the commit before"
      
      and the reason is that Will moved the test for whether we need to flush
      from tlb_flush_mmu() into tlb_flush_mmu_tlbonly().  But that meant that
      tlb_flush_mmu_free() basically lost that check.
      
      Move it back into tlb_flush_mmu() where it belongs, so that it covers
      both tlb_flush_mmu_tlbonly() _and_ tlb_flush_mmu_free().

      x86: mm: fix VM_FAULT_RETRY handling · cf3c0a15
      Linus Torvalds authored
      My commit 26178ec1 ("x86: mm: consolidate VM_FAULT_RETRY handling")
      had a really stupid typo: the FAULT_FLAG_USER bit is in the 'flags'
      variable, not the 'fault' variable. Duh,
      
      The one silver lining in this is that Dave finding this at least
      confirms that trinity actually triggers this special path easily, in a
      way normal use does not.

        The second part prepares for a cleanup of the fuse device I/O code by
        adding a helper for simple request submission, with some savings in
        line numbers already realized"

      mksnap reply only contain 'target', does not contain 'dentry'. So
      it's wrong to use req->r_reply_info.head->is_dentry to detect traceless

      Probably this code was syncing a lot more often then intended because
      the do_sync variable wasn't set to zero.
